I have flowerhorn who prefers to live alone. I used to have another Texas cichlid with it. As the flowerhorn grew larger, dominating nature grew and it killed the Texas cichlid. I feed him shrimp and worm . The fish likes to dig nest of shelter on the base of the aquarium. He lives in a 500 L aquarium. Now he is 35 cm and is really colourful. If a shelter and many small chips of stones are provided to the fish, a chance of colour enhancement can occur as it finds a good natural environment.

Flowerhorn is one of the most aggressive kind of fishes ever. You need a large tank due to their adult size (can grow as long as 40 cm head to tail if you are really really lucky), and if you put an adult male and female together they might try to breed and at the same time try to wipe out ALL of the other fishes in the tank. However if you put them together along with a lot of other aggressive fishes they tend to become more peaceful and fish friendly. Do not put them together with ultra aggressive fishes such as red devils, because they will get killed. They are very easy to breed, and the better your tank environment, the better the fish grows.

The flower horn is not a wild cichlid. It is a domestic hybrid of many American cichlids. The flower horn is a hardy fish. This fish gets brilliant colors if maintained properly. This fish is not favorable for community tanks. It is very aggressive. If fed live food it can grow very quickly. New varieties of this fish are being bred with different colors.

I have kept flower horns for about 10 years now. Overall I have had good experiences with them, I have kept about 200 or so and I must say flowerhorns, midas and red devils are my favorites. I have kept 4 in one tank that was about 2000 liters and they were still very territorial. These fish are hardy but are very very aggressive if left in a small tank. I have gotten a few to mate over the years and I must say that it was a privilege to see these monsters grow from these wimpy fish into these beautiful catchers. I would not suggest these for beginner aquarist because of the price tag.

I have a young flowerhorn, about 7 cm big. It's just killed my firemouth which was about the same size as the flowerhorn. I also have a female convict and it doesn't seem to want to go anywhere near the flowehorn. Flowerhorns are really nice fish and I feed mine frozen food as well as pellets.

Flowerhorns are extremely aggressive species and I think their deep red eyes confirms it to an extent. A little salt can really enhance their colour. No other fish can withstand their terror and cruelty. They will almost try to gulp down the samller ones and terrorize other large fish, eventually killing them. I had a tiger oscar in the same tank which was newly intoduced, and within seconds the flowerhorn sucked its eye. Having only a single eye it eventually died. Now I have a zebra convict which is 4 cm and my flowerhorn has grown to 28 cm, but the little buddy is giving the monster a tough competition. It just looks at the flowerhorn like if telling him "come on, let's have a fight" and the flowerhorn doesn't dare to go near the convict. My flowerhorn has never bitten me while cleaning the tank, I always clean with bare hands without any protection.

I have a stunning male flowerhorn in a 200 L corner tank. He lives alone as he was attacking the plecos that were with him, but he's happy. He wasn't cheap, he's a grade A show quality specimen and set me back 250 UK pounds. He's about 15-17 cm and eats pretty much anything from live, frozen, flake and pellet.

I have two 18 cm flowerhorns in a 300 L aqurarium who are thriving. They are extremely aggressive and killed the third flowerhorn with which they were introduced. I keep them with a 23 cm red devil with which they battle occasionally. I keep their territories separate with large pieces of driftwood. They also don't seem to bother my two 20 cm plecos. These are my second set and I have found that they do well if you can manage to break up territories appropriately.
